HERMANN SCHUPPISSER, OF ZURICH, SWITZERLAND.

GAS-REGULATOR FOR INCANDESCENT LIGHTS.

Specification of Letters Patent.

katented June 12, 1906.

Application filed April '7, 1905. Serial No. 254,296.

Be it known that I, HERMANN SOHUPPIS- sER, a citizen of the Republic of Switzerland, residing at Zurich, in Switzerland, have invented new and useful Improvements in Gas-Regulators for Incandescent Lights, of which the following is a s ecification.

Gas-consumption regu ators in which the gas-supply to the burner is regulated by means of a bell-valve introduced into the mixing-tube through the mouth of the jet and which is adjustable relatively to a valvecone so that the width of the opening is varied in proportion to fluctuations of pressure of the gas present are known. In these regulators a regulation of the gas consumption only takes place and not a regulation of the air-supply to the mixingtube.

According to the present invention the bell-valve is guided upon a valve-pin and is so arranged that it simultaneously regulates the amount of air supplied to the mixingtube, so that an approximately constant mixing ratio is maintained between the amount of gas and air supplied to the mixingtube. For this purpose the bell-valve is ar ranged to work in a conically-widening mixing-tube. The accompanying illustrative drawings show one construction of the improved regulator.

Figures 1 and 2 are central vertical sections through the regulator, with portions thereof in elevation. In Fig. 2 parts are shown displaced by the gas-pressure. Fig. 3 is a horizontal section corresponding to the line A B of Fig. 1; and Fig. 4 is a plan, the parts being in the same position as that they occupy in Fig. 3

The regulator is arrangedin a casing that is formed with a vertical screw-threaded hole b for attachment onto a gas-pipe and with a funnel-shaped enlargement with which the hole I) is in communication. Steps 0 are turned in the wall of this funnel-shaped enlargement, and upon these steps rest weights formed as disk-rings d. The lower portion of a vertically-movable bell f extends through the rings d, while the upper portion of said bell extends closely through a head or cap 6, screwed onto the casing a. At its lower end the bell f has a flange g, which is located below the lowest or first weight (1.

h indicates a regulating-pin carried by the casing a and extending centrally through the bell, its upper end being formed with a cylindrical head i, that closely fits the central opening in the top of the bell through which it extends. The head i, which acts as a guide to the upper part of the bell, has formed round its periphery five equally-distributed vertical gas-outlet grooves is, each increasing in depth downwardly. Ribs lat the lower part of the pin h form gas-passages n between them and also serve to guide the lower part of the bell.

Upon the head or cap e is arranged a mixing-tube m, the central axis of which conincides with the central axis of the bell f and which at its lower part has a conical form corresponding to the upper part of the bell. The inclination of the conical portion of mixing-tube is similarly directed, but at a diiierent angle to the inclination of the conical upper part of the bell.

The operation of the improved regulator is I as follows: Gas flows. through the passages n into the bell f and through the five outletopenings surrounding the head '1' and formed by the grooves 7c and the opening provided for the passage of the regulating-pin head i in the top of the bell into the mixing-tube m for the purpose of being there mixed with a suitable quantity of air. The weight of the bell corresponds at this time to a determined pressuresay that corresponding to a twentymillimeter water-columnbelow which the gas-pressure is not able to lift the bell or below which the bell remains in the position shown in Fig. 1. If now the gas-pressure increasessay from that corresponding to a twenty-millimeter water-column to that corresponding to a thirty millimeter watercolumnthe bell will be lifted until by its flange 9 it lifts the first weight, so that the bell will be then weighted by a certain amount, and it is thereby able to exert counter-pressure to the gas-pressure corresponding to a thirty-millimeter water-column and remain in its raised position. The lifting of the bell has caused it to move upon the head 'i, whereby the five gas-outlet openings 7c have become smaller, because the grooves decrease in depth toward the top. If the gas-pressure still increases, the bell f rises still more, all the weights being ultimately raised thereby one after the other. (See Fig. 2.) With the rise of the bell the crosssection of the five gas-outlet openings k decreases more and more.

The grooves 7c in the head 'i are arranged in such manner that the product of the outflowspeed of the gas and the cross-section of the outlet-openings formed by the grooves 7c and the bell is constant in any position of the bell. For the production of a uniform flame correct regulation of the air-supply to the mming-tube is also necessary in addition. This regulation of the air-supply is effected by' making the up er part of the bell project into the conical y-formed lower part of the mixing-tube, so that as the bell rises it decreases the annular space located between it and the mixing-tube more and more. By this means the speed of the air drawn in increases with the increased gas-pressure. By suitably shaping the upper part of the bell, as well as the lower part of the mixing-tube, the speed and amount of the drawn-in air can be so controlled that the gas-and-air mixture is a good and eflicient one at any gas-pressure, the complete combustion of the mixture being thereby insured. When the gas pressure falls, the bell sinks and unloads itself gradually from the weights by depositing them upon the steps. The weights may be so calculated that at a pressure corresponding to a thirty-millimeter water-column one weight is raised, and at each addition of pressure corresponding to a ten-millimeter watercolumn a further weight is raised in order to be able to maintain with the bell the necessary counter-pressure to the gas ressure.
